24 Claims. (012101-57) This is a division of my application, Serial No.469,953, filed July 23, 1930;

This invention relates to printing machines of the kind wherein aplurality of printing devices 5 are introduced into a magazine and fromwhich they are withdrawn and fed through printing position, whereatimpressions are made therefrom, and then to a galley wherein theprinting devices are collected in the same sequence as that in whichthey were arranged when introduced into the maagzine whereby thecollected printing devices may be removed from the galley and stored indrawers of storage cabinets until they are to be used again.

The printing machines are ordinarily so arranged that the printingdevices move therethrough in a step-by-step manner and an impression ismade from the printing device at printing position during an at restinterval in the step-by-step movement. Not all of the printing devicesmoved through printing position are always used in a printing operationand a selector mechanism, which cooperates with identifying means on theprinting devices, determines which of the printing devices are to beused in a printing operation. Often it is desired to make more than oneimpression from the printing devices from which impressions are beingmade and to this end the step-by-step movement of the printing devicesis interrupted while the platen of the machine is making the desirednumber of impressions after which the step-by-step movement of theprinting devices is resumed.

Among the objects of my invention are to in-' the selector mechanismwhile multiplicate impressions are being made from a printing device andto render the selector operative as the last of the multiplicateimpressions is being made; to constantly operate the driving device forimparting a step-by-step movement to the printing devices but to providea portion separable from the constantly driven device so that thestep-bystep movement of the printing devices is interrupted withoutaltering the constant operation of said driving device; and to providefor multiplication by a simple and economical construction of efficientand positive operation and which may be readily installed in printing,machines of various designs without requiring extensive altertionstherein.

Fig. 6 is a fragmentary detail view of a shifting mechanism; and Fig. '7is a fragmentary detail view of a portion of the controlling deviceforming the --subject matter of this invention. 1 I have illustrated myinvention in associa tion with a printing machine embodying a jack shaft8 having a pulley arrangement 9 or other suitable power'receiving devicefast thereon to which movement is imparted from a suitable source ofpower such as an electric motor (not shown). On'the jack shaft 8 is apinion 10 meshed with a spur gear 11 rotatable on the main drive shaft12. A controlling rod 13 is provided for engaging the clutch 14 toconnect thespur gear 11 to the shaft 12 whereby movement imparted to thepulley 9 will be transmitted through jack shaft 8, pinion 10, spur gear11 and clutch 14 to said drive shaft 12. The jack shaft 8 and the driveshaft 12 are journaled in suitable-bearings in the frame 15. The tableor bed 16 of the machine is mounted at the upper end of this frame. Atone side of the machine and carried by the bed 16 is a magazine M intowhichprinting devices D are introduced and from which the printingdevices are successively withdrawn and fed to printing'position above ananvil whereat impressions are made therefrom by the platen P through asuitable ink ribbon (not shown). The platen P is mounted at the lowerend of the housing 17 at the outer end of the platen arm 18 pivotalabout the shaft 19 carried by the frame of themachine. Formed as anextension of the platen arm 18 is an arm 20 which depends below theshaft 19. At the lower end of thearm 20 is'a half-round lug 21. An arm22 is'pivotally mounted at 23 on a bracket 24 depending from the bed16.. A notch 25 is provided in the upper edge of the 'arm 22 and the lug21 seats in'this notch :to latch the platen in its upper or nonprintingposition,-as shown and described in my co-pending application, SerialNo. 572,489, filed November 2, 1931.

In my co-pending application, Serial No. 469,953, filed July 23, 1930, Ihave described a selector mechanism for controlling the operation of theplaten from the printing devices. This selector mechanism includes ahead H wherein a plurality of detecting fingers F are mounted and whichare positioned by engagement with identifying characteristics on theprinting devices. When the fingers are positioned they cooperate with amatrix to regulate the positioning of'the arm 26 which, in turn,regulateslthe positioning of the arm 27 which has an upstanding portion28 at the free end thereof on which there is a triangularly shaped lug29. Pivotally mounted at 23 is a vertically extending arm 30. having anotch 31 therein and a formed end portion 32. A triangular portion 33 isdefined between the notch 31 and the forward end 32 and the apex thereoflies in the plane of the front edge 34 of the portion of the arm belowthe notch 31, Whenever the arm 26 isso positioned that the upwardlyextending portion 28 of the arm- 27 is so located that the triangularlyshaped lug-29 seats on either the edge 34 or the apex of the projection33, the arm 30 is pivotedinto 1 the position shown in Fig, 2 and the arm35,

connected to the arm 30, is also pivoted. A spring 36 extends betweenthe arms 22 and 35 and when the arm 35 is pivoted as described, thespring 36 is tensioned whereby the arm 22 is moved downwardly and thenotch 25 isretracted from engagement with the lug 21 whereupon the arm18 is free to pivot about the shaft 19 so that the platen P will movetoward printing position. Should the triangular-1y shapedportion 29 be.positioned in either the notch 31 or along the formedend 32, the spring37 will act on the arm 22 to pivot it into an upper position whereat thelug 21 will seat in the notch 25 to latch the platen in its upper ornon-printing position. When the platen arm is released in the mannerdescribed so that the platen may move toward printing position,impression pressureiwill be imparted to the arm at the time the platenmoves into a predetermined position. To, regulate the time at whichimpression pressure will be imparted to the platen, I provide an arm 38'having a cam surface 39 thereon. A dog 40; is pivotally mounted at 41 onthe arm 20 and the nose 42 of this dog travels along thecam surface 39as the platen P moves toward printing position and at the time theplaten P moves into a predetermined position relative to the printingdevice D in printing position, the nose 42 reaches the end of the camsurface 39 and the spring 43 acts to pivot the dog whereby the shoulder44 thereon moves into the line of movement of the shoulder 45 on the arm46 unitary with the clamp strip 47 surrounding the eccentric 48 fast onthe main drive shaft 12, for at the time the platen P is moving towardprinting position the eccentric operates to move the arm 46 outwardlyawayfrom the shaft 12. As soon as an impression has been made by theplaten P the hooked end portion 49 on the arm 46 engaging a boss 50 onthearm 20 moves the platen P away from printing position into its upperor non-printing position for at this time the eccentric is moving thearm 46 toward the shaft 12. A. platen operating mechanism-of theforegoing type is preferablyemployedin the machine because it affords asafety in that printing pressure is not applied to the platen until thetime it is in aposition so close to the printing low the guideway 51 isa center bar 52 having a plate 53 on the upper edge thereof on which theprinting devices D rest during movement from the magazine throughprinting position and to the receiving. galley, and this plate ispreferably of a width equal to the distance between the spacing flangeson the printing devices so that the printing devices will neatly fit onthe plate during movement therealong. Extending in juxtaposition to thecenter bar 52, on each side thereof are rails 54 and 55 and mountedinwardly of the rail 54 is a slide bar 56 having driving pawls 57mounted thereon which are urged upwardly by springs 58. At therear endof the slide bar isa shoulder 59 which engages the lowermost of theprinting devices in the magazine M and as the slide bar moves toward theleft, as viewed in Fig. 1, the lowermost of the printing device is movedfrom the magazine onto the plate 53. The surface of the slide bar56behindthe shoulder 59' is in a plane above the remaining portionthereof, and. this surface holds the printing devices in themagazineabove the lowermost printing device against displacement as theshoulder 59 moves said lowermost printing device onto the plate 53. Theslide bar receives a reciprocatory movement and the pawls 57 engage theprinting devices during movement of the" slide bar to the left in Fig. 1to advance the printing devices toward printing position and thereceiving galley. When the slide bar moves toward the right as viewed inFig. 1, suitable stop pawls (not shown) engage the printing devices tohold them against movement and the pawls 57 are cammed downwardlyagainst the action of the springs 53 and pass below the'printing devicesso that when movement of the slide bar to the right is completed each ofthe pawls will have moved the entire length of one printing device andwill have been moved by the springs 58 into engagement with the end ofthe printing device behind that previously engaged thereby and underwhich they have just moved.

The slide bar, as has been stated, has a reciprocatory movement impartedthereto. One end of a rod 60 is connected to an arm 61' pivotally,connected to the slide bar at 62. The other end of the rod is pivotallyconnected to the upper end of a rocker 63 mounted onrthe stub shaft 64journaled in a portion 65 which is a part of the bracket 24. Anotherrocker 66 (Fig 3) is fast on the: stub shaft 64 adjacent the rocker 63'.On the rear face of the rocker 66 and at the edges are projectingflanges 67 and68 which provide a trackway 69 therebetween'. Disposed inthis trackway is a roller 70 carried by the crank 71 mounted at the endof a shaft 72 journaled in the bracket 24. On the shaft 72 is a bevelgear 73 meshing with a bevel gear 74 fast on the main drive shaft 12 andwhen the main drive shaft 12 is rotated movement is transmitted throughthe bevel gear 74, bevel gear 73, and shaft 72 to the crank 71 and asthe crank 71 rotates the roller 7.0 reciprocates in the guideway 69 andimparts a rocking movement to the rocker 66. On the rocker 66 is aprojecting lug which extends past the edge of the rocker 63. Pivotallymounted at '76 on the rocker 63 is a pawl .77 having a notch '78therein. adapted'to engage the lug 75 to thereby interconnect the rocker63 to the rocker 66, a spring '79 holding the notch in engagement withthe lug. So long as the notch 78 is engaged with the lug 75, the rocker63 will rock with the rocker 66 and this rocking movement will beimparted through the rod 60 and arm 61 to the slide bar 56 wherebytheprevious- 1y referred to reciprocatory movement will be imparted tosaid slide bar. When morethan one impression is to be made fromaprinting device the operation of the means feeding thev printingdevices is interrupted and this may be conveniently accomplished bydisengagingthe notch '78 from the lug 75 without interrupting movementof the rocker-66. To this end anarm 80 is pivotally. mounted .at 81 onthe bracket24. A pin 82 is mounted at one end of the arm 80.and rests onthe inclined pin 83. A rod 84-is passed through the pin 82and aspring 85is disposed about this red between the pin 82 and the adjusting nuts 86at the outer end of the rod. The rod 84 may be extended to a manuallyoperated lever whereby when the rod is depressed the pin 82 will act onthe pin 83 to pivot the pawl '77 whereby the latch '78 will bedisengaged from the lug 75. This arrangement is employed when it isdesired to manually interrupt operation of the printing device feedingmechanism. However, means to be described hereinafter and cooperatingwith the arm 80 function to automatically disconnect the printing devicefeed when multiple impressionsare to be taken from a printing device.

' The present machine is arranged so that consecutive, duplicate,triplicate, or quadruplicate impressions may be taken from each printingdeviceand while I have shown an arrangement limited to the making ofquadruplicate impressions it is tobe understood that an arrangement formaking a greater number may be provided if so desired. Suitablysupported on the bracket 24 is a stud 8'7 carrying a shaft on which'aplurality of peripherally notched discs are rotatably mounted. Thesediscs are rotated by a pawl 88 pivotally. mounted on the outer end of anarm 89 having a bearing portion 90 through which the shaft 19 isextended. Depending from the bearing portion 90 is a boss 91 and aspring 92 extends between the bracket 24 and the boss 91, and thisspring urges the arm 89 upwardly. An adjusting screw 93 is'mounted inthe arm 89 and has a lock nut 94 thereon. .The free end of the adjustingscrew 135 engages one edge of the arcuate arm 95 (Fig. 4) that isconnected to and extends at ri ht angles from the platen arm 18 andabout the shaft 19. When the platen moves downwardly, aspreviouslydescribed, an edge of the arcuate arm 95 engages the screw 93 and pivotsthe arm 89 downwardly against the action of the spring 92. A spring 96extends between the pawl88 and the arm 89 and urges the free end of thepawl into engagement with a shield 97 carried by the bracket 24 anddisposed over the peripherally notched discs mounted on the shaft 8'7.In the present instance, where the device isarranged for consecutive,duplicate, triplicate, and quadruplicate, operation of the platen,threesuch discs are provided and these discs are indicated by 98, 99 and109, and the. shield 97 is slightly wider than the three discs andthe-spacing therebetween. The disc 98 is engaged byfthe pawl 88whenduplicate impressions'are to be made from a printing device and inthe present construction of the machine this disc has twelve notches inthe periphery Y thereof. .The' disc 99 is used when triplicateimpressions are to be made from a printing device and has eighteennotches in the periphery thereof- The disc 100 is used whenquadruplicate impressions are to be made from a printing device and thisdisc has twenty-four notches in the periphery thereof. ."Ihe pawl 88rests on the shield 97 and this shield is used to withhold the pawl fromengagement with the notches in the disc until a certain time, for whenthe pawl engages the disc 98, having twelve notches therein, 'moremovement is imparted to the disc than is imparted to the disc 100 whenit is engaged, for. this disc has twenty-four notches therein;

therefore, the portion of the shield aligned with the disc 98 is cutaway, as indicated at 101, to permit the pawl to engage the disc 98 nearthe start of an operation of the pawl and to continue in engagementduring most of the period of operation; The shield 9'7 is also cut"away, as indicated 'at 102, in alignment with the disc 100, but as asmaller portion of the shield is cut away in this instance the pawlwillonly engage the disc for a short period during its operation.

Intermediate the cut-away portions 10land 102 the shield is cut away, asindicated at 108, and

this cut-away portion permits the pawl to-engage the disc 99 for aperiod longer than itengages the disc 101' but not as long as it engagesthe disc 98. The remaining portion 104 of the shield is not cut awayand, therefore, when the pawl is aligned with this portion ofthe shieldit will merely ride thereover and will not engage any disc, and thisarrangement is used when but one impression is to be made from aprinting device. To bring about automatic control of the engagement ofthe notch 78 with the lug 75 I provide the following arrangement. An arm105 is pivotally mounted on the bracket 24 at 106. This arm includes areduced portion 107 through which the screw 108 is extended, said screwengaging .a' reduced portion 109 on the arm 80 at the endthereofopposite the pin 82. One end of the arm 105 extends through anopening 110 (Figs. 2 and 3) in the bracket 24 and is disposed below thepin 111 mounted at the upper end of the arm. 112 that is pivotallymounted at 113. .On the arm 112, below the pivotal mounting 113, is apin 114. Extended through the discs 98, 99, and .100, are six pins 115equidistantly and circumferentially spaced in the discs. As six pins areprovided, the discs are notched in multiples of six and the discs havebeen described as having twelve, eighteen and twenty-four notches intheperiphery thereof. When the machine is arranged for consecutiveoperation, the pm 114 remains engaged with one of the pins 115. i Aspring 116 extends between the bracket 24 and the arm 112 and acts onsaid arm to hold the pin 114 in engagement with a pin 115. When the pawl88 is moved into alignment with, for example,

the disc 98 having twelve notches therein, and

the spring 116 pivots the arm 112 to cause the pin 111- to movedownwardly. Downward movement of the pin 111 similarly pivots theengaged end of arm 10.5 and, therefore, the end of arm 1.05 bearing: thescrew 1 08 moves: upwardly. This pivots the arm which, causes the. pin82'. to move along the inclined portion of the pin 83- to disengage thenotch 7.8 fromthe lug '75 and to thus disconnect the rocker 63. from.they rocker 66 which, as previously pointed out, disconnects theprinting device feed. The screw 1118 is adjustable and, therefore,.theamount. of movement imparted to the arm 80 may be. easily varied. Uponthe next. operation, of. the pawl. 88,. the. disc 98 will again be movedone-twelfth of a revolution. It has been pointed out that there are sixof the pins 1.15 and that these pins are equidistantly andcircumferentially spaced; therefore, when the first one-twelfth: of arevolution was imparted to the disc 98', the disc was rotated in anamount suflicient to. dispose the pin 114 midway betweenv two of thepins 115. Thus, when the latter one-twelfth. of: a revolution is.imparted to the disc, the succeeding pin 115 will be moved intoengagement with the pin-114 and. this. will pivot the arm 112 upwardly.A spring 117 extends between the arms and 80 and holds the ends of thesearms in engagement with each other. Therefore, when the pin 111 moves upwardly, the end of the arm 105 carrying'the screw 108 will movedownwardly and the spring 117 will act to reposition the arm 80 in theposition illustrated in Fig. 1 and thus the rocker 68. will bereconnected to the rocker 68 and the printing device feed willagainfunction. Shouldthe pawl 88 be aligned with the disc 99 and thepawl then be operated, it will move over the shield 97 and will engageone of. the notches of the disc 99 and will impart to said discone-eighteenth of a revolution. This will disengage one of the pins pfrom the pin 114, and, the printing device feed will be disconnectedwhen downwardmovement of the pin 111 occurs. However, under thiscondition, the pin 114 will be-disposed one-third of'the distancebetween the pins-115 and thus upon the next operation of the pawl 88the-disc 99 will again be moved one-eighteenth of a revolution and thesucceeding pin 115 will not engage the pin 114 and, therefore, theprinting device feed will again not operate. However, on the next.operation of the pawl 88 the disc 99 will again be moved oneeighteenthof a revolution and during this operation the succeeding pin 115will'engage the pin 114 and, therefore, the printing device feed willagain be placed in operation. It is therefore apparent'that when thepawl 88 is aligned with the disc 98 the printing devicefeedisinterrupted on alternate operations of the'machineand when the pawl isaligned with the disc 99 the. printing device feed is interrupted fortwo consecutive operations of the machine and is not reengaged until thethird successive operation. Thus, since twenty-four notches'are providedin the disc 100, it is apparent that the disc will be rotated butone-twenty-fourth of a revolution on each operation of the pawl 88therefore, when apin 115 is disengaged from the pin 114 the succeedingpin will not engage the pin 114 until the fourth. following operation ofthe pawl 88. vAs the pawl 88 is operated with the platen, it controlsthe opera-- rod 11.9; is connected to: the; bearing. portion; 90 and theother endv is mounted. in the. bifurcation in the lever 121 (Fig. 6).The. lever 1 21 is fixed on a, shaft 122; that is supported at the rearedge. of: the bed 16. A handle 123 is; connected tothe shaft; 122 and ismovable into registration with suitable indices on: the upper surface ofthe bed. which indicate the setting, lock:- ing means. of approved. formbeing; provided to retain the. handle. in registration with, differentones of theindices. As best. illustratedin. Fig. 7, suitable springwashers 124 are. disposed between the discs 98, 99, and. 100, and thesespring washersv exert sufficient tension onthe. discs to. preventturningv thereof other than that. caused. by the pawl.- 88.,

At the time the. head H of theselector mechanism moves into the positionillustrated in.Fig.. 2 whereat the fingers F are engaged with theprinting. device in selector position,.thearm 27. is:moved into a.downward position and the triangularly shaped lug 29 rests on the edge34 and as; has been, previously described, when the lug rests: on thisedge, the arm 22 isso pivoted that the. notch 25 is disengaged from thelug 21 so that the platen arm is unlatched. As the platen moves downewardly into printing position, the pawl 88. acts on the disc with whichit is aligned, in event said pawl is aligned. with one of the discs, andmoves the pin. 115 from engagement with the pin 114 whereupon the spring116 pivots the army 112: in a clockwise direction as viewed inFi'g. 2.At the lower end of the arm 112 there is a shoulder 125 and on the arm.27 there is a lug 126 having a flattened face. The. pin 115 will.disengage. the pin 114 at the time the arm 2'7 is. in. the positionillustrated in Fig. 2', which, as previously stated, is a time at whichthe triangularly shaped lug 29 is. engaging the edge 34 and the fingers.F are engaging the printing device in selector position. When the arm27 is in this. position the flat surface on the lug 126 is below theplane. of thehorizontal portion of the shoulder 125 and consequently,due to the influence of the spring 11.6, the shoulder will move abovethe flat surface on the lug 126 and these parts will be held. in. en.-gagement by the spring 127. Consequently the head H will be held in a.position whereat the fingers will remain in engagement-with the printingdevice. in selector position and thelug, 29 will remain in engagementwith the edge 34. In a manner previously described, the feed of theprinting devices will have been interrupted and consequently, whenthe-platen returns to: its upper oirnon-printing position, it mayimmediately start to descend into printing position to make an.impression from the printing device from which. an impression waspreviously made for this printing device will remain in printingposition. If the device is arranged for making duplicate impressions,the. succeeding. pin 115 will, upon the second descent. of the: platen,engage. the pin 114, whereby the shoulder 125 will be disengaged fromthe lug. I26. Consequently, the parts. may function as determined by theselector mechanism. If the device is arranged for triplicate orquadruplicate impressions, the succeeding pin 115 will not yet engagethe: pin 114 .and hence the shoulder 125' will remain in engagement withthe lug 126 and the platen will make another operation so that at. leastanother impression will be madeirom the; printing device in printingposi' tion. It is therefore apparent. that the multiplicator forming thesubject matter of -this invention not only arrangesgforirepetitiousoperation of the platen but also renders the selector inoperative untilthe last of the repetitious im-.

pressions is made by the platen.

It is manifest from the foregoing description that I have provided amultiplicator which may be easily set up so that consecutive, duplicate,triplicate, or quadruplicate impressions will be made from the printingdevices. The set-up of the mnltiplicator is determined by a manuallymovable handle conveniently located in the bed of the machine. Furtherthe multiplicator not only brings about interruption of the feed of theprinting devices but likewise releases the platen latching arrangementso that it will not move into latching position until the desired numberof impressions have been made. Moreover, the multiplicator renders theselector inoperative in a manner such that the selector again becomesoperative and determines the operation of the machine as the last of therepetitious impressions is being made. The device is of simple andeconomical construction and is efiicient and positive in operation andmoreover it embodies but. a few parts which may be arranged at aconvenient location in the machine tothereby facilitate servicingthereof. t

In the foregoing description I have illustrated and described a selectedembodiment of my invention but it is to he understood that this iscapable of variation and modification and I there-' fore do not wish tobe limited tothe precise details set forth but desire to avail myself ofsuch changes and alterations as fall within the purview of the followingclaims:
